Elymoclavine is an ergot alkaloid (ergoline alkaloid). It can be produced from C. fusiformis from Pennisetum typhoideum. It is a precursor in the biosynthesis of D-(+)-lysergic acid. Ergot alkaloids are natural products derived from L-tryptophan. They are often toxic for humans and animals. Despite that they are also well known for their pharmacological activities.[1][2]
